Recently I came across a device that tracks the GPS position and has additionally a card reader (http://photofinder.atpinc.com/). If you plug in a card with photos it will integrate location data into the jpgs using time as common reference.
It is a further interesting example where software moves away from the generic computer/PC (where such programs that use a GPS track an combine it with photos are available, e.g. GPS photo linker) into a appliance and hence the usage complexity (on principle, did not try it out so far this specific device so far) can be massively reduced and the usability can be increased. See the simple analysis:
Tangible Interaction using the appliance:
- buying the device
- plug-in a card
- wait till it is ready
vs.
GUI Interaction:
- starting a PC
- buy/download the application
- install the application
- finding an application
- locating the images in a folder
- locating the GPS track in a folder
- wait till it is ready
.. could become one of my future examples where tangible UIs work đ
